REGENERATI VE-BETORT BENCH.

Application filed March 28.

To all whom it may concern:

B0 it known that I. REZEAL' B. lhtowx, a citizen of the United States, residing at Mil- Waukee, in the county of Milwaukee and Stateof 'Wisconsin, have invented a new and uszful Improvement in Regenerative-lictort Benches, of which improvement tho follow in r is a specification.

y invention relates to improvements in gas furnaces and particularly in the construction of the passages of ducts through which the air pauses from the ext rior to the combustion chamber and passages through which the wastaeproducts of combustion [Ml-S from the otnnbu'stion chamber to the exterior.

The objects (if my invention are to Jro dine a construction of air pznsages which can be varied or changed so a to came the 8i! (0 citclllabexmore or lwgs rircuitonely in its passage the combustion chamber and thus, by in contact with the heated Manges a longer or shorter ptriod, vary the tam erature of the air introduced into the com ustion chamber dependent upon exist ing conditions and requirement.

Another object. of my invention is to so construct said air and waste product passages, independently of the furnu 'iand bench walls so that the expansion and Irontractiun of the furnace and bench walle will not seriously affect the same.

A further object of my invention in to so construct said air passage: as to enable the chan e and variation therein, and the clraning t aereofi'to be readily effected from the front without disturbing the furnare and bench walls; and to accoinplhh these sevvrul objects my invention (,OllfilwiS in the now-l f of ho mnport and are capable of being poconstruction and arrungmin-nt of part: hero inafter more specifically dwwrihwl, rot'ewnm bein had to the accompanying drawings, in whic Figure 1 indirateia a front elevation in tron chamber more or losection, of my improvrmenti Fig. 3 indi cates a longitudinal 5 (film: on line a; Fig. 1.

1 claim 11 my invention and desire to secur by Letters Patent: l

1. In a gas furnace, he combination with j a ombustion chamber. "as retort bench, and I cparated ombustion chamber and retort bcH lt walk, of lines or ducts lo ated between the walls of the combusti n chamber and retort bench and separated therefrom; by .-pa econatitutingr additional fines, and adjurtnblc baflles located in said spaces and I independent of said walls.

3. In a gas furnace, the ('ml'lbllltltlOH with a combustion chamber, ea: retort bench. and tcparated combustion chamber and retort! icnch walk, of llues or ducts located be! tween the walls of the combuetion chamber and retort bench and separated therefrom by spaces conetituting additional fines, and 1 batlics located in said spaces and adjust-l abl supported by the flue; or ducts and in dependent of said walls. I

MPtll'ilfld combustion chamber and retort bench walls, of flues or ducts remorably lo cated between the walls of the combustion chamber and retort bench and supported indepeudentlv of the walls aforesaid and separated therefrom by space constituting additional llues and adjustable battles slidably mounted in said spaces and inde endent of naid Walls and said first named ue.

i. In a gas furnace. the combination with a combustion chamber. gas retort bench, and eparated combustion chamber and retort bench walls, of transverse supports removably arranged at intervals between the walls aforesaid but independent thereof, tile resting on said supports in superposed relation, thereby forming inner and outer fines or ducts, and adjustable b'allles slidably mount ed on the ends of the supports and located letween the tile and the walls aforesaid, and independent of said walls.

7. In a gas furnace, a recuperator con j tructed and supported entirely independent of the walls on either side of it -so as to be entirely removable without interference with any part of the furnace, and sliding battle Dupported by said recuperator entirely independent of the furnace walls.
